Hi Clint, I'm guessing you are using vagrant. The thing is cassandra-chef-cookbook use template cassandra.yaml.erb, where you can find: "broadcast_address: <%= node[:cassandra][:broadcast_address] %>" which in turn is equal to "node[:ipaddress]". Value of node[:ipaddress] depends on how do you con

Re: unstable write performance

2014-03-26 Thread Marcin Cabaj
ParNew GC (used by default in cassandra) uses 'stop-the-world' algorithm, which means your application has to be stopped to do gc. You can run jstat command to monitor gc activity and check if your write performance is related to GC, eg: $ jstat -gc 1s But it shouldn't drop throughtput to 0 ops/s.
